Abstract
In some embodiments a system and method are described for safeguarding a hazard, the hazard, for example a needle point, may be moved between a protected retracted position, an active extended position and/or an intermediate position. Optionally in the retracted position, the hazard may be protected inside a housing. Optionally in the extended position, the hazard may be exposed. Optionally, in the intermediate position the hazard may be partially protected and/or concealed, for example by a shield and/or in an indentation. In some embodiments, compromising a shield causes the hazard to be retracted to the retracted position.
